BACKGROUND

1. Field of Use

This invention relates to bed covers and more particularly to an adaptable foot warmer/blanket held securely in place by detachable means.

2. Description of Prior Art (Background)

During the winter months and especially in colder climates, the need to keep warm is a pervasive problem. This becomes particularly acute when an individual retires for the evening. Conventional bedding including sheets, blankets, bedspread, comforter, etc., when-used in total, can become quite cumbersome to the user and some individual's feet are quite sensitive to the extra weight of multiple covers. In particular, one's feet, being outer extremities of the body, are more prone to becoming cold especially during the inactive time when one is in bed. In order to solve the cold feet syndrome, normally, one simply adds additional layers of covers to a degree sufficient to warm the feet. Of course, when the feet are finally sufficiently warm, the remainder of the body can become uncomfortably warm. In persons with medical conditions such as circulatory problems and diabetes, cold feet are chronically a problem and, in environments such as hospitals and nursing homes, conventional full body covering may not be practical.

Known efforts to solve this problem have centered around various methods of modifying existing bedsheets and/or covers by permanently attaching additional components normally in the form of a pocket-like feature for the purpose of receiving one's feet. Of course, such an arrangement is expensive and makes it more difficult to make up a bed. Such arrangements, being permanently affixed to bedsheets and covers, eliminate the ability to utilize conventional bedsheets and covers if additional foot warmth is desired.

Other known efforts include a foot warmer which, in combination with a bed having a mattress and box springs, provides additional warmth for a user's feet and comprises a fabric pocket having a width approximately equal to the width of the bed and having permanent attachment straps extending downwardly from the sides of the pocket under the mattress and above the box springs. These straps make it more difficult to remove the foot warmer. In addition, installing the foot warmer requires one to wrestle the foot warmer straps under the mattress; a difficult task for the elderly and handicapped.

Other efforts in the prior art is for sheet construction to arrange the configuration of the sheet into a desired form. Depending on the nature of the prior art proposal the sheet construction will provide an expandable sheet for different purposes. By way of example, U.S. Pat. No. 2,567,072 to Kay discloses a tubular sheet which fits over a mattress in an “envelope” fashion. U.S. Pat. No. 2,636,191 to Bate discloses a sheet which can be folded to serve as both upper and lower sheets for a narrow bed. U.S. Pat. No. 2,637,860 to Lehigh discloses a compound bed covering. Different layers are sewn together using double-folded edges. U.S. Pat. No. 2,895,146 to Lester discloses a reversible cover for pillows, mattresses or the like. U.S. Pat. No. 3,331,088 to Marquette discloses a blanket with separate panels which can be attached or detached to increase or decrease the thickness and hence the warmth.

DETAILED DESCRIPTION

In the drawing, the numeral 1 generally indicates a conventional bed having box springs 2 adjoined in known manner to headboard 3. Mattress 4 is situated atop box springs 2.

According to this invention, a foot warmer is provided and is shown in detail in FIG. 2. More specifically, the foot warmer comprises a fabric pocket 6 which is formed from generally rectangularly shaped fabric material. Material generally suitable for blankets has been determined to be highly desirable for purposes of this invention although any suitable thermal retentive materials could be satisfactorily utilized.

As best seen in FIG. 1, the pocket portion of the foot warmer has a width approximately equal to the width of the bed 4 on which it is used and an adjustable length extending from the foot end of the foot end of the bed sufficiently to cover only the feet portions of a user, below the knees of a user, the length being substantially smaller than the length of the bed.

In order to form pocket 6, the rectangular piece of material is folded over along end edge 7 to form upper and lower fabric sheets which are removeably connected along side edges 8 and 9. Pocket 6 then appears as shown in FIG. 3 which is closed on end 7 and sides 8 and 9. Of course, by this means, formed in pocket 6 is opening 10. It will be appreciated that connected side edges 8 and 9 may be connected by any suitable means which allow for the edges to be easily unconnected and reconnected as desired and to adjust the depth of pocket 6. For example, the edges may have appropriate strips of Velcro, zippers, or even buttons 15A as shown in FIG. 2, distributed along the edges 8 and 9. Another example, but not limited to, is shown in FIG. 4. Attachment rings such as D-rings 41, or any other suitable ring or fastener is connected to pocket 6 along edges 8 and 9 via elastic straps 42. It will be appreciated that two D-rings 41 are shown along each edge 8 and 9 but any suitable number of D-rings or suitable fasteners may be used. It will also be appreciated that the D-rings may be any suitable material such as plastic or metal.

In order to secure pocket 6 to bed 1, detachable means is provided in the form of attachment straps 11 and 12 which are secured along the upper ends thereof by detachable means such as, for example, buttons 15A, zippers, or Velcro, respectively, to edges 8 and 9.

Attachment straps 11 and 12 may be expandable in order to accommodate varying sizes of mattresses. The completed foot warmer then appears as shown in FIG. 2. It will be appreciated that having detachable means distributed along edges 8 and 9 allows for the foot warmer to be adjusted for position along the length of the bed. It will be further appreciated that having detachable means along edges 8 and 9 will allow for the foot room in the warmer to be adjustable.

Referring to FIG. 5A and FIG. 5B attachment straps may be elastic straps 51, each with hook 52 and loop 53 Velcro disposed along the elastic strap 51.

When used in conjunction with bed sheet 5 on mattress 4, as shown in FIG. 1, the foot warmer, as shown in FIG. 2, is placed at the foot end of the bed with opening 10 facing headboard 3. This is accomplished by slipping the detachable means in the form of attachment straps 11 and 12 under the mattress so that the attachment means is disposed between box springs 2 and mattress 4.

It will be appreciated that the detachable straps may be left under the mattress 4 when it is desired to remove the foot warmer for cleaning or to use the foot warmer independent of the mattress 4, e.g., sitting in a chair.
